The NASA spacecraft unveils the unique environment of Jupiter Moon



  NASA Finds Water Fountains on Europe (Jupiter's Moon), Indicates Strange Life

About twenty years later, in 1996, Jupiter's largest moon, known as Ganymed, surprised scientists when astronomers learned it was the only one Moon, which builds its own magnetic field. This unique magnetic field surrounding Jupiter's Moon, unlike any other planet in our solar system, has brought to light some newly obtained information.

The new data comes from NASA's Galileo spacecraft, which flies past the planet Venus and two asteroids. It has been orbiting and gathering information about the planet's largest planet for about eight years. At that time, all data received from the spacecraft had not been analyzed. A team of scientists is now working together and decides to look back to it.

NASA's Galileo spacecraft, which is slightly larger than a fully grown giraffe, had its first flyby of the moon about two decades ago. The spacecraft worked by sending back findings on the moons of the gas giant. The mission ended in 2003. However, the newly discovered data from the first flyby of the Galileo spacecraft, as detailed in the Geophysical Research Letters journal, provided insights into the Moon's environment.

The Ganymede, which is the only largest moon in our solar system, as analyzed by scientists, could potentially cause a huge liquid ocean to slosh beneath its surface. It could only be a niche where extraterrestrial life could protect itself.

Author Glyn Collinson, the lead investigator at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said that they are now dating back over 20 years later to take a fresh look at some of the information that has never been published and that Have finished history. He added that they found out there was a whole piece that nobody knew about.

Consistent with the newly obtained results, there could be a stormy scenario in which particles were displaced by the incoming plasma from the icy surface of the moon. Rain and violent plasma currents passed between the largest planet of our solar system and its satellite through an eruptive magnetic events between the magnetic environments of the two bodies.

The Ganymede has Auroras, more specifically the northern and southern lights. The particles responsible for the auroras appear from the plasma surrounding the planet. At the time of Galileo's initial Ganymede flyby, the spaceship randomly crossed the auroral regions of the Jupiter satellite, as evidenced by the ions that rained on the surface of the Moon's polar cap. As the researchers believe, such findings may prove key to revealing the secrets of the moon, such as why the Ganymede's auroras are so bright.

Planets possessing magnetic environments, known as magnetospheres, have undoubtedly been revealed and very well known. But it was never expected that a moon possesses one. From the time of Jupiter's arrival until the year 2000, the Galileo spacecraft made six targeted fly-bys of the Jupiter's moon with numerous instruments for gathering information about the magnetosphere of the moon. The results also included the spacecraft's plasma subsystem (PLS), which estimated the temperature, density and direction of the plasma that flows around the Galileo through the environment.
